The 2017 Coquimbo earthquake and resulting tsunami was a deadly event that occurred between 0424 - 1532 UTC. The main event lasted 6 minutes, 24 seconds, throwing the seabed up by 5 meters in some areas, whilst causing subsidence of 3 meters along others. The resulting tsunamis were 44 meters high in some areas, which either washed people out to sea, battered them with debris, or both at the same time. The biggest aftershock of the event occurred at 1244 UTC, and was a magnitude 8.4, shaking the areas affected by the main shock for a further 2 minutes, which sent another tsunami ashore. In all, 35,216 people died, 122,410 were injured, and total damages reached $22 billion, making it one of Chile's worst disasters.
